    Abstract: A pump beam (12) is subjected to pulse front tilting, and then guided through an imaging optics (30) and then coupled into the nonlinear optical medium through an entry surface of the nonlinear optical medium. THz radiation is generated in the optical medium by nonlinear optical processes, in particular by optical rectification, via the pump beam. The pulse front tilt of the pump beam required to satisfy the velocity matching condition of vp,cs cos(?)=vTHz,f is induced as a sum of a plurality of pulse front tilts, where each pulse front tilt is induced separately as a partial pulse front tilt of the pump beam in subsequent steps. The last step of pulse front tilting of said pump beam (12) is performed by coupling the pump beam (12) into the nonlinear optical medium through a stair-step structure (40) formed in the entry surface of the nonlinear optical medium.

A plurality of integrated photodetectors is formed in a bottom substrate so as to detect the light through the slit and generate signals correlated to the light through the slit. The area of the slit varies with the rotation angle of the platform and causes diffraction, more or less marked as a function of the angle. The difference between the signals of two photodetectors arranged at different positions with respect to the slit yields the angle.

  • Patent number: 10088359
    Abstract: Presented here are devices and methods to correct ambient light measurements made in the presence of optical elements, such as the curved edge of the cover glass associated with the mobile device. In one embodiment, a film with optical properties is placed within the ambient light sensor to diffuse the high-intensity light beam coming from the optical element. In another embodiment, an aperture associated with the ambient light sensor is disposed to prevent the high-intensity light beam from entering the ambient light sensor. In another embodiment, a processor coupled to the ambient light sensor smooths the peak associated with the high intensity light beam produced by the optical element.

  • Patent number: 10082426
    Abstract: The present invention provides a spectrometer, comprising: an inlet for the receipt of incident light; an optical path for transmitting the incident light from the inlet to an analysis plane; a focusing element located along the optical path, wherein the spectrometer has an in-focus position in which a focal point of the spectrometer and the analysis plane coincide; and a controller adapted in use, when a removable light disperser is placed along the optical path, to cause the spectrometer to be in the in-focus position by controlling the position of the focusing element relative to the analysis plane. The spectrometer is used in the analysis of light from a light source and, due to the ability of the controller to manage the focus point by way of moving the focusing element, the spectrometer is able to bring itself into an in-focus configuration without the need for a user to intervene.

  • Patent number: 10067352
    Abstract: A tool for capturing a three dimensionally viewable image. The tool includes multiple reflective surfaces for generating one view of a scene whereas another view of the same scene from a slightly different location is obtained free of the reflected surfaces. Both views may be simultaneously captured by the lens and displayed together in a single image. Thus, a variety of sterographic techniques may be utilized for viewing the image in a three dimensional manner.

  • Patent number: 9995626
    Abstract: A confocal microscope, operable to focus on any of a plurality of portions of a sample, is optically coupled to a light source and to a spectrograph module. When the confocal microscope focuses on a particular portion of the sample, the confocal microscope directs incident light from the light source to the particular portion and directs responsive light from the particular portion to the spectrograph module. The spectrograph module can be operated using a first diffraction grating having a first line density to obtain a Raman spectrum of the responsive light from the particular portion of the sample. The spectrograph module can also be operated using a second diffraction grating having a second line density that is less than the first line density to obtain a fluorescence or phosphorescence spectrum of the responsive light from the particular portion of the sample.

  • Patent number: 9977069
    Abstract: In a non-contact discharge test performed in a poor electromagnetic noise environment, the energy of discharge is evaluated by detecting weak light emission and processing the intensity waveform of light emission of the discharge. A database is created by measuring the intensity waveform of light emission of discharge generated as a result of application of a voltage or current to a measurement object through use of a light emission measuring device, simultaneously measuring the current waveform of the discharge through use of a current measuring device, and storing in the database the relation between analysis data sets obtained through analysis of the waveforms on the basis of information of the voltage or current applied to the measurement object. The intensity waveform of the light emission of the discharge or spark generated from the measurement object is measured while an electromagnetic wave generated as a result of the discharge of the measurement object is used as a reference.

  • Patent number: 9976905
    Abstract: Since both gloss and a reflection characteristic are measured by one surface characteristic measurement device, a gloss measurement target area and a reflection characteristic measurement target area are appropriately set. A gloss measurement instrument and a color measurement instrument are integrated with a gloss colorimeter. The gloss measurement instrument illuminates an illumination target face by illumination light, receives reflected light generated by a regular reflection of the illumination light on the illumination target face, and outputs a measurement result for the reflected light. A size of the gloss measurement target area can be changed. The color measurement instrument illuminates the illumination target face by annular illumination light, receives reflected light generated by a reflection of the annular illumination light on the illumination target face, and outputs a measurement result for the reflected light. A size of the reflection characteristic measurement target area can be changed.
